B. positron
C. neutrino
D. helium-4

Answers

Answer 1
Answer: A type of antimatter created in some nuclear fusion reactions within stars is B. Positron. Antimatter is composed of antiparticles, and is considered to be the opposite of matter. Its antiparticles have the same mass as ordinary particles, but they have the opposite charge. When matter and antimatter come into contact, annihilation or destruction occurs.

If you double the distance between two objects, the electric force is _____.A. one half as strong

B. doubled

C. one fourth as strong

D. quadrupled

Answers

Answer:

decreases one fourth of the original value.

Explanation:

according to coulomb's law the electrostatic force of attraction and repulsion magnitude is directly proportional to the product of magnitude of charges and inversely proportional to their distance (square distance).

So increases in distance between two charges results in decrease of electric force between two charges.

Answer:

C. one fourth as strong

Explanation:

Electric force is indirectly proportional to the square of the distance, so if you double the distance, electric force is = 1/2^2 = 1/4

In short, Your Answer would be: Option C

What usually happens to the host’s DNA during the lytic cycle?

Answers

The lytic cycle is one of the two phases of reproduction in viruses. In this part of reproduction, the viral RNA joins with the DNA of the host and copies itself into the host's DNA pattern. This will cause the host cells to reproduce the viral cells instead of the original host cells. Overtime as the viral cells continue to reproduce they will overload and eventually cause the host cell to explode. When this occurs, then the produced viruses will continue on to infect the next cell.
